To all whom it may concern:

Be it known that .l, Framers T. SARGENT, of New York city, county, and State, have in rented a new'and Improved Process for ()riniiiienting Glass; and i no hereby declare the following to be a foil and exact description of liifijiilYfiiliiOll, which wiii enable others skilled in the art to which it appertaiosorlwith which it is nicstclosel y con neeted to melienso of the,

. My invention has for its oigiect to produce a cheap substitute for the expensive colored glass now so extensively used for advertisingeigiis and other purposes; and itconsists, prii5 mariiy, in a new process, to he hereinafter more fully described, for imparting to ordinary plain or ground glass the appearance of ornamented colored glass; and, secondly, in a new article of maniifacture nainely, the pro- 7 9o d ict of'the process alluded to.

In carryingniyimproved process into praciice'I take gelatine and impart to it any desired shade or tint of color by means of any coloring-matter that will dissolve thoroughly.

move the parts of the gelatine not affected by light and leave the other parts. It isthen al' lowed to dry. The surface is next covered with daniinar varnish, or alike coating, which, when dry,preven ts its being afiected by water.

Plain glass surfaces can thus be prepared with any design and in any colorat a trifling cost, and with little labor, compared with the production of the same designin ordinary colcred glass.

I am aware that it is not new in the art of photography to print pictures uponglass plates covered 'with colored and sensitized goiatine by means of photographic negatives and a washingprocess, and such I do not, therefore, broadly claim; but

\Vhat I do claim as my invention is- 1. Theherein-described process of ornanienting 'Iassin imitation of colored or stained glass-namely, by coating the glass with a film of colored sensitized gelatine, printing upon said sensitized film by means of a negative and catposure to light the design to he reproduced, washing away the parts not aii'r'ected by light, and, finally, applying a coating of varnish, substantiallyias set forth.

2. Asa new article of manufacture, signs, ornaments, &c., consisting of glass surfaces having colored gelatine' designs permanently aliixeil thereto, substantially in the manner described FB-i-LNOlS (if. SARG'ENT.
